Safety precautions for
maintenance

WARNING

Before performing any maintenance,
turn   the   selector   switch   with   the
removable key to the "OFF" position
and   disconnect   the   battery.   This
prevents   the   generator   from   being
activated unexpectedly.

WARNING

Prevent risks of an electrical nature
by disconnecting the power from the
board   before   performing   any
maintenance   by   means   of   the
specific key selector, isolating both
the main disconnecting switch (CP.1)
and   the   load   disconnecting   switch
and disconnecting the battery.

6.3

Electrical maintenance
interventions

DANGER

Verify   there   are   no   residual
voltages   before   disassembling   a
device   or   making   contact   with
parts of it. Pay particular attention
when   working   on   circuits
connected   to   capacitive   loads
(capacitors)   or   on   external
connections   of   which   you   are   not
sure of their isolation.

NOTE

Pay attention when handling
electronic

circuits.

Many

components   are   subject   to   being
damaged or broken by electrostatic
charges   and   therefore,   also   from
contact made with the human body.
Touch an isolated metal structure to
discharge   your   potential   charge
before working on the component.

NOTE

Do   not   use   compressed   air   to
remove the dust during the cleaning
operations of  the electrical system.
Blowing   compressed   air   inside   the
panel can cause the components to
break and the conductors to loosen
from their clamps.

6.3.1

General checks on the
electrical system

Verify there is no water or condensation
infiltration

•

Make sure there is absolutely no water infiltration

or the formation of hazardous condensation.

•

Promptly check the sealing systems (gaskets).

•

Immediately remove water and perform the

necessary repairs.

Verify the tightness of the cables and
components

•

Check the tightness of the power cables and

connection bars.

•

Check the tightness of the clamps and wires on

the terminal boards by pulling the cables lightly.

•

Check the tightness of all the fixing screws of the

components, both in the control board and on the
generator.

•

Tighten the screws when necessary.
